BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofJamesbrittenia plant, botanically known as Jamesbrittenia hybrida,commonly referred to as South African Phlox and hereinafter referred toby the name ‘INJAMSASKY’.

The new Jamesbrittenia plant is a product of a planned breeding programconducted by the Inventor in Heidesheim and Gensingen, Germany. Theobjective of the breeding program is to create new compact,freely-branching and uniformly mounding Jamesbrittenia plants with earlyand freely flowering habit, attractive flowers and good gardenperformance.

The new Jamesbrittenia plant originated from a cross-pollination made bythe Inventor in August, 2017 in Heidesheim, Germany of Jamesbritteniahybrida ‘Shakira Yellow’, not patented, as the female, or seed, parentwith a proprietary selection of Jamesbrittenia hybrida identified ascode number Ja 16 15-6, not patented, as the male, or pollen, parent.The new Jamesbrittenia plant was discovered and selected by the Inventoras a single flowering plant within the progeny of the statedcross-pollination in a controlled greenhouse environment in Heidesheim,Germany in July, 2018.

Asexual reproduction of the new Jamesbrittenia plant by vegetativeterminal cuttings in a controlled greenhouse environment in Gensingen,Germany since July, 2018 has shown that the unique features of this newJamesbrittenia plant are stable and reproduced true to type insuccessive generations.

SUMMARY OF THE INVENTION

Plants of the new Jamesbrittenia have not been observed under allpossible combinations of environmental conditions and culturalpractices. The phenotype may vary somewhat with variations inenvironmental conditions such as temperature and light intensitywithout, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘INJAMSASKY’. These characteristics incombination distinguish ‘INJAMSASKY’ as a new and distinctJamesbrittenia plant:

-   -   1. Compact, upright to outwardly spreading and mounding plant        habit.    -   2. Vigorous growth habit and rapid growth rate.    -   3. Freely branching habit; dense and bushy plant form.    -   4. Early and freely flowering habit.    -   5. Single-type flowers that are light reddish purple and white        in color.    -   6. Relative resistance to Botrytis.    -   7. Excellent garden performance.

Plants of the new Jamesbrittenia can be compared to plants of the femaleparent, ‘Shakira Yellow’. In side-by-side comparisons, plants of the newJamesbrittenia differ primarily from plants of ‘Shakira Yellow’ inflower color as plants of the new Jamesbrittenia have light reddishpurple and white-colored flowers whereas plants of ‘Shakira Yellow’ havebright yellow-colored flowers.

Plants of the new Jamesbrittenia can be compared to plants of the maleparent selection. In side-by-side comparisons, plants of the newJamesbrittenia differ primarily from plants of the male parent selectionin flower color as plants of the new Jamesbrittenia have light reddishpurple and white-colored flowers whereas plants of the male parentselection have red-colored flowers.

Plants of the new Jamesbrittenia can be compared to plants ofJamesbrittenia hybrida ‘INJAMSADAW’, disclosed in a U.S. Plant Patentfiled concurrently. In side-by-side comparisons, plants of the newJamesbrittenia differ primarily from plants of ‘INJAMSADAW’ in flowercolor as plants of the new Jamesbrittenia have light reddish purple andwhite-colored flowers whereas plants of ‘INJAMSADAW’ have purple andbright yellow-colored flowers.

Plants of the new Jamesbrittenia can also be compared to plants ofJamesbrittenia hybrida ‘Goldstar’, not patented. In side-by-sidecomparisons, plants of the new Jamesbrittenia differ primarily fromplants of ‘Goldstar’ in the following characteristics:

-   -   1. Plants of the new Jamesbrittenia are more vigorous than        plants of ‘Goldstar’.    -   2. Plants of the new Jamesbrittenia are more freely branching        than plants of ‘Goldstar’.    -   3. Plants of the new Jamesbrittenia have a stronger root system        than plants of ‘Goldstar’.    -   4. Plants of the new Jamesbrittenia have light reddish purple        and white-colored flowers whereas plants of ‘Goldstar’ have        yellow-colored flowers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations andmeasurements describe plants grown during the late summer and earlyautumn in 10.8-cm containers in a corrugated polycarbonate-coveredgreenhouse in Carlton, Mich. and under cultural practices typical ofcommercial Jamesbrittenia production. During the production of theplants, day temperatures averaged 26° C., night temperatures averaged20° C. and light levels averaged 9,290 footcandles. Plants were pinchedthree weeks after planting and were ten weeks from planting rootedcuttings when the photographs and description were taken. In thefollowing description, color references are made to The RoyalHorticultural Society Colour Chart, 2015 Edition, except where generalterms of ordinary dictionary significance are used.
